Description

Technical Field

[0001] This utility model relates to the field of drainage pipeline technology, specifically a municipal drainage pipeline for urban planning. Background Technology

[0002] Water pipes refer to the system of pipes and their ancillary facilities that collect and discharge sewage, wastewater and rainwater, including main pipes, branch pipes and pipes leading to treatment plants. Regardless of whether they are built on streets or anywhere else, as long as they serve the purpose of drainage, they should be counted as drainage pipes. However, when the urban planning municipal drainage pipes currently in use divert rainwater, the rainwater brings garbage from the road surface when it flows into the drainage pipes, and the garbage will accumulate and easily cause blockage of the drainage pipes.

[0003] Patent document CN215253300U discloses an urban planning municipal drainage pipe, including a pipe body. A blocking block is fixedly connected to the inner wall of the pipe body, and a water-dividing plate is fixedly connected to the outer surface of the blocking block. An inlet is formed on the inner wall of the pipe body, and a transfer device is fixedly connected to one side of the inlet. An outlet is fixedly connected to the inner wall of the pipe body, and a filter screen is fixedly connected to the surface of the outlet. A disassembly hole is formed on one side of the transfer device. This urban planning municipal drainage pipe differs from conventional drainage pipes. The transfer devices on both sides of the pipe body allow soil to reach the transfer devices without affecting the normal operation of the water passages. Furthermore, it can divert water when the flow rate is high. The water passages can handle the main drainage, and the blocking blocks facilitate the flow of garbage to the transfer devices, keeping the garbage within them. The disassembly cover allows for easy removal and cleaning of the garbage inside the transfer devices.

[0004] Although the existing technology can collect filtered impurities through a transfer device, the pipes are buried in the ground with the pipe openings flush with the ground, which also buries the transfer device. This makes it difficult to remove the cover and clean the inside of the transfer device. Therefore, a new type of urban planning municipal drainage pipe is proposed to optimize the existing technology. Utility Model Content

[0005] The purpose of this utility model is to provide an urban planning municipal drainage pipeline to solve the problems mentioned in the background art.

The upper part of the filter screen 2 is provided with a conical filter section 3, and the lower part of the filter screen 2 is provided with a cylindrical filter section 4. The pipe body 1 is provided with a discharge port 5 on the bottom circumference corresponding to the conical filter section 3. The pipe body 1 is provided with a drain hole 6 on the circumference corresponding to the cylindrical filter section 4. The outer side of the pipe body 1 is provided with an outer sleeve 7. The bottom end of the outer sleeve 7 is fixedly connected to a reducing pipe 8. The reducing pipe 8 is fixedly connected to the pipe body 1 and is flush with the drain hole 6. The top of the outer sleeve 7 and the top of the pipe body 1 are provided with a first placement groove. A cover plate 9 adapted to it is placed in the first placement groove. The cover plate 9 is provided with a lifting hole. The top of the pipe body 1 is provided with a second placement groove. A grate plate 10 adapted to it is placed in the second placement groove.

[0024] The filter screen 2 filters the incoming water from the pipe. Filtered impurities slide down through the conical filter section 3 and are discharged into the outer casing 7 through the discharge port 5. Simultaneously, the impurities are drained through the drain holes 6 in conjunction with the cylindrical filter section 4, leaving the impurities inside the outer casing 7. The interior of the outer casing 7 can be easily cleaned by opening the cover plate 9. The cover plate 9 is flush with the grate plate 10, allowing for direct opening and cleaning without digging.

[0025] A connecting pipe 11 is fixedly connected to the bottom outer side of the pipe body 1, and a connecting plate 12 is fixedly connected to the end of the connecting pipe 11. The connecting plate 12 is used to connect with other external pipes.

[0026] A cross-shaped reinforcing rib 13 is fixedly connected to the filter screen 2, which increases the overall support strength of the filter screen 2.

[0027] The bottom inner side of the tube body 1 is fixedly connected to the bottom surface of the filter screen 2. The filter screen 2 can be supported at a fixed height by connecting the support plate 14, which is convenient for alignment with the discharge port 5 and the drain hole 6.

[0028] The filter screen 2 is placed directly on the tray 14, which makes it easy to lift and remove the filter screen 2 for cleaning.

[0029] A support column 15 is fixedly connected to the cross-shaped reinforcing rib plate 13. A support cylinder 16 is sleeved on the outside of the support column 15. A stop piece 17 is fixedly connected to the bottom end of the support cylinder 16 and the top end of the support column 15. The stop piece 17 at the bottom end of the support cylinder 16 is slidably sleeved on the outside of the support column 15. The stop piece 17 is provided to form a sliding fit and prevent detachment between the support column 15 and the support cylinder 16. The stop piece 17 at the top end of the support column 15 is slidably connected to the inside of the support cylinder 16.

[0030] A stop plate 18 is fixedly connected to the top of the support cylinder 16. The stop plate 18 rests against the bottom surface of the grate plate 10. A spring 19 is provided between the support cylinder 16 and the support column 15. The spring 19 is inserted into the support column 15. A slot is provided on the support column 15 for the spring 19 to be inserted.

[0031] The support cylinder 16, support column 15 and spring 19 form an elastic extension and contraction, thereby squeezing the abutment plate 18 through the grate plate 10, so that the filter screen cover 2 can abut against the support plate 14, forming a stable placement effect.

[0032] The working principle of this utility model is as follows:

[0033] In use, rainwater passes through the grate plate 10 and enters the pipe body 1. The rainwater entering the pipe body 1 slides down through the conical filter section 3, causing impurities to slide down along the conical filter section 3. It then enters the outer casing 7 through the impurity discharge port 5 and slides down through the reducing pipe 8 to the drain hole 6. It is then drained by the cylindrical filter section 4. Finally, the impurities are retained in the outer casing 7 and the reducing pipe 8, thus creating a collection effect. After the impurities accumulate, the outer casing 7 can be cleaned by opening the cover plate 9. When the mesh of the filter screen 2 becomes clogged and affects the water leakage, the grate plate 10 can be opened, the filter screen 2 can be taken out and cleaned, and then the filter screen 2 can be put back into the pipe body 1 and supported by the support plate 14. At this time, the grate plate 10 is closed, and the grate plate 10 presses against the abutment plate 18. The abutment plate 18 presses against the support cylinder 16, thereby compressing the spring 19. The support column 15 presses the filter screen 2 downward, so that the filter screen 2 falls stably on the support plate 14.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
